Expecto Patronum! JK Rowling dedicated Deathly Hallows, her seventh and final Harry Potter book, to her mum, sister, husband and children. She arranged the words in the shape of Harry’s lightning-shaped scar. Visit the Harry Potter Lexicon to see all the secrets behind this dedication.

The dedication of this book is split seven ways:
to Neil,
to Jessica,
to David,
to Kenzie,
to Di,
to Anne,
and to you, if you have stuck with Harry until the very end.

Here’s an adorable dedication from Tony Hsieh, CEO of Zappos.com, Inc (and a big-time brand builder long before Zappos started zipping shoes around the world). Tony wrote “Delivering Happiness” about all the joy (and hard times) that Zappos survived… such as moving from the lush bay area to Las Vegas, and merging with giant Amazon. He dedicated it to Ava.
